Tomato to be "Master Browser:?

I'm playing around with some stuff today.
I've had my NAS box being the master browser but decided to make sure Tomato wasn't doing it.
Browstat says my Vista desktop is the master browser and it doesn't show over half the computers on the network, which FreeNAS did, but it does show a bunch of uPNP shares \=

Since Tomato is handling the DHCP, can it be configured to be the master browser as well?

I don't think I can help you, but I'd like to learn what you mean by "master browser." Normally when I read browser I think of a web browser, but you seem to be talking about file sharing on a LAN. So, what do you mean? I'm curious and I'd like to learn.

I had to do some looking myself today
From my understanding a Master Browser will find all the computers on a network and make the names available when another computer browses the network i.e. open "My Network Places" on a windows machine.

As mentioned there was a distinct difference between FreeNAS handling it and my Vista desktop.

hmmm... Is the Master Browser handled by Samba? If so It doesn't look good for Tomato.
